* Floating point emulation is enabled for non-coprocessor PC's. We
apologize for this oversight in the release of DEU 5.2. The team member
responsible has been severely punished (forced to watch a week of A TEAM
reruns).

* A better routine for aligning X textures has been added.

* Minor cosmetic changes in the usage message and command line prompt.

I used it between 1994-2000, and then moved to WinDEU. Today I use Yadex, a DEU variant for Unix. I've tried other editors -DCK, Wadauthor-, but was never confortable with them, and always returned to the good old DEU derivatives. DEU was awesome.
